Using Arduino with ESP32 MINI (newbie)

Postby leotordo » Thu Feb 02, 2023 2:02 pm

Hello everybody.
Sorry but I'm newbie in ESP32 World.

I developed a simple application with ESP-WROOM-32 Dev Kit Board (like AZ Delivery board for example).
I connected USB cable and with IDE I wrote my code.

Now I want to use ESP32­C3­MINI­1 module

I've some questions
  • Is the virgin EPS32C3MINI1 that I buy on Digikey (for example) ready to be connected to Arduino IDE via UART or needs to be programmed first?
  • On ESP32CMINI1 application schematic I see external oscillator. Is there an internal oscillator? I've not to much space on my board
Thank you all
Stefano

Hi,

You can flash an unprogrammed ESP32-C3 using Arduino IDE.
If you talking about pins 12 and 13 on the MINI1 module, these pins are the low-frequency crystal (32kHz). Internally on the module, you will find only the high-frequency crystal (40MHz).
